Fogging is a fumigation method spraying insecticide vapour.
It is ineffective in reducing mosquitoes.
It is common that mosquitoes are still running rampant a few hours after fogging.
For survival, mosquitoes come in waves.
Another wave of mosquitoes comes only after one wave is no longer in the area.
They do not come all in once.
Furthermore mosquitoes grow resistance towards the insecticide.
The root cause is not tackled.
Mosquitoes breed in water so mosquito larvae are unharmed.

There are collateral damages from fogging.
Although publicized as harmless to humans, it is demonstrated otherwise by the mask-wearing worker.
Some workers even use a truck-mounted fogger to minimise contact with the vapour.
A joke can be made: Humans die before mosquitoes do with the fogging.
Other animals can be killed by fogging unintentionally.
House cleaning is necessary after fogging with oil-based solution.

If someone offers to do fogging in our house, just decline politely.
Also make a complaint to the municipal council about chemical toxicity if fogging is frequently done in the neighbourhood.
Stopping fogging will benefit the whole society because resources are not wasted.

Effective way to reduce mosquito population is biological control, such as release of the mosquito larvae predator fish (e.g. goldfish or Gambusia) into the drain.
Severe punishment on litterbugs is also needed.
Many people like to throw rubbish into the drain, causing blockade that creates mosquito breeding ground.
Many more people like to litter and a lot of litters, such as the drinking can, is capable of collecting rainwater.
